Definitions
- the present invention relates to a UV disinfecting system for waste water and drinking water including a cleaning device having the features of the preamble of Claim 1.
- low-pressure mercury radiators or medium-pressure mercury radiators are used, which are protected by cladding tubes and immersed into the water to be treated.
- the radiators and the cladding tubes are made from UV permeable material. In practice, quartz glass is used for this.
- the external surface of the cladding tubes is in direct contact with the surrounding liquid, and this is where any material depositing during operation over time separates from the surrounding liquid. This may be inorganic material such as, for example, lime. However, these may also be deposits of organic material.
- a radiation system is provided with a cleaning apparatus which is disposed on irradiation chambers.
- the apparatus is mounted rigidly on the chambers wherein a cleaning fluid is used for washing of the dirt which deposited on the chambers.
- DE 600 19 106 T2 shows cleaning elements having elastomer rings and a chamber which is formed between two rings, respectively, into which rings a cleaning agent is to be fed.
- DE 603 12 598 T2 shows a cleaning device comprising cleaning elements made from a wire material.
- the cleaning elements are elastically biased against the cladding tube surface and, during the cleaning operation, are driven in the axial direction of the cladding tube as well as additionally for rotation about the longitudinal axis.
- DE 101 25 507 A1 shows a purely mechanically acting cleaning ring comprising a guide chamber and blades orientated vertically relative to the cladding tube surface in the guide chamber.
- the blades are configured as a helical ring which extends elastically around the cladding tube surface and, due to its elasticity, rests against the surface.
- This cleaning device adjusts itself to compensate for any wear.
- a high surface pressure of the cleaning ring against the cladding tube surface is achieved.
- water bodies having a tendency to cause severe incrustations on the cladding tubes the effect diminishes over time.
- the scraper ring is mounted radially slidable in the cleaning ring and is configured to be pressed radially towards the cladding tube by the pressurized fluid, pressure can be applied onto the scraper ring from the pressurised fluid in the direction of the cladding tube and thus a uniform high contact pressure against the cladding tube surface can be achieved, which is additionally controllable via the applied pressure.
- a common pressure source and a common drive may be used for a larger system having a plurality of radiators.
- the cleaning ring has a number of nozzles in the axial direction in the vicinity of the scraper ring, which nozzles are vertically or obliquely directed towards the surface of the cladding tube, are arranged in the circumferential direction of the cleaning ring at a distance from one another and are spaced from the surface of the cladding tube, because in this way any coarse dirt accumulations may initially be removed in a contactless manner, which means they will not put any stress on the scraper ring. In this way, a longer service life of the scraper ring will be achieved and any scratching of the cladding tubes by the scraping motion will be reduced.
- the drive of the cleaning rings has a resting position in an end position in the axial direction of the cladding tubes and the nozzles are moved ahead of the scraper ring in respect of a movement from this end position. Then, in the case of an initial actuation after a longer break period, the coarse deposits will be removed first, before the scraper ring slides over the cladding tube surface.
- nozzles are in communication with the supply means for a supply of pressurised fluid under elevated pressure
- a common pressure source for the nozzles and the contact pressure of the scraper ring may be used.
- Any electric driving components may be completely dispensed with, if the drive of the cleaning rings in the axial direction of the cladding tubes is carried out hydraulically, for example by means of a hydraulic cylinder.
- the drive may be carried out electrically or hydraulically if a spindle drive is used as the drive.
- the drive may in particular be fed with the pressurised fluid.
- a cleaning ring is generally identified with the reference numeral 1.
- the cleaning ring 1 comprises a two-piece base body 2 having a base portion 3 and a cover ring 4.
- the cover ring 4 is fastened to the base portion 3 with threaded screws 5.
- the base body 2 has a first connection 6 for a pressurised fluid.
- the cover ring 4 supports a scraper ring 7 made from a plastic material, said scraper ring being retained in a first groove 15 in the cover ring 4.
- a section 8 having a diameter that is reduced compared to that of the base body 2 is provided.
- Section 8 has a groove for receiving a securing ring 9 and is used for retaining the cleaning ring 1 in a device.
- nozzles 10 can be seen, which are implemented as through bores and are open towards the inside.
- the cleaning ring 1 is approximately rotationally symmetric relative to an axis extending vertically in Figure 1 and surrounds an annular clear opening, into which nozzles 10 are directed.
- Figure 2 shows a longitudinal section of the cleaning ring 1 along a longitudinal axis 11. Identical components are identified with the same reference numerals.
- the cover ring 4 is provided with a first groove 15 that is open towards the longitudinal axis 11.
- the first groove 15 has a rectangular cross section.
- the scraper ring 7 is inserted into the first groove 15 in such a way that it can radially slide therein, but seals against the groove walls.
- the base portion 3 of the cleaning ring 1 is also provided with a continuous second groove 16 which is open towards the longitudinal axis 11.
- the second groove 16 is covered on its open interior side with an insert 17 which is coaxially disposed in the base portion 3 relative to the longitudinal axis 11.
- the insert 17 supports the nozzles 10 already described, which are implemented as radial through bores and are in communication on the one hand with the second groove 16 and on the other hand with the internal space surrounded by the cleaning ring 1.
- the insert 17 further supports the section 8 having a tapering cross section, which section includes the securing ring 9.
- a bore 12 disposed parallel to the longitudinal axis 11 connects the grooves 15 and 16.
- the first connection 6 from Figure 1 is not shown. This first connection is in communication with the second groove 16 and consequently also with the first groove 15.
- Figure 2 further shows sections of a cladding tube 18 which is arranged concentrically to the longitudinal axis 11 and which in operation surrounds a UV radiator which is also orientated concentrically relative to the longitudinal axis 11.
- the UV radiator is not shown here to improve clarity.
- the scraper ring 7 rests against the external surface of the cladding tube 18 with two continuous lips 19.
- An annular gap is provided between the insert 17 and the surface of the cladding tube 18.
- Figure 3 shows the cut-out III from Figure 2 in an enlarged view. Identical components are again identified with the same reference numerals. The cladding tube 18 is not shown in this view.
- the base portion 3 is sealed with an O-ring 20 against the cover ring 4 in the area of the bore 12.
- the insert 17 is sealed against the base portion 3 with two further O-rings 21.
- the second groove 16 is in communication, as already described, with the nozzles 10 and with the first connection 6.
- the first groove 15 is sealed radially inwards by means of the scraper ring 7 resting against the groove walls. In this way a system of spaces is obtained which are located within the cleaning ring 1 and which are open towards the outside only through the first connection 6 and the nozzles 10. As a result, an application of pressure onto the first connection 6 and thus onto the second groove 16 will lead to an increase in pressure in the second groove 16, the bore 12 and the first groove 15.
- the fluid introduced there under pressure flows through the nozzles 10 radially inwards into the gap between the insert 17 and the cladding tube 18.
- the corresponding increase in pressure in the first groove 15 generates a force which pushes the scraper ring 7 radially inwards, i.e. towards the cladding tube 18.
- Figure 4 shows a device, wherein a total of nine cleaning rings 1 are arranged in a common holder 25.
- the holder 25 comprises a connection tube 26, holding elements 27 and connection elements 28.
- the holding elements 27 are of essentially equal design and each hold three cleaning rings 1 and they are arranged at such a distance from one another that one cleaning ring 1 of each holding element 27 is respectively aligned with a second and a third cleaning rings 1 in relation to the longitudinal axis 11.
- the connection elements 28 keep the holding elements 27 spaced apart and parallel to one another.
- connection tube 26 Inside of the connection tube 26, a channel is disposed which may be fed with pressurised fluid via a second connection 29.
- the connection tube 26 is hollow and is in communication with corresponding channels in the holding elements 27, which in turn are in communication with the first connections 6 of the cleaning rings 1.
- an application of pressure on the second connection 29 leads to the above-described condition, wherein the scraper rings 7 are pressed radially inwards and the pressurised fluid exits from the nozzles 10.
- pressurised fluid flows through the components 26, 27 and 29 which are used as supply means from the pressure source to the cleaning ring 1.
- FIG. 5 The integration of the described device in a system for irradiating water in a closed radiation channel 34 made of stainless steel is shown in Figure 5 .
- the connection tube 26 is arranged here below the holding elements 27.
- each of the holding elements 27 supports three cleaning rings 1, of which only two, respectively, can be seen in this view.
- three UV radiators 30 are provided, which are mounted inside the cladding tubes 18. In this way, the UV radiators 30 are protected from direct contact with the water present in the radiation channel 34. However, the external surfaces of the cladding tubes 18 are in direct contact with the water.
- An electric motor 31 having a corresponding transmission drives a spindle drive 32, which in turn is used to drive the holder 25 parallel to the axis 11.
- water is fed through a connection fitting 33 into the radiation channel 34.
- the water flows around the cladding tubes 18 and exits the radiation channel 34 again at the opposite end through a corresponding fitting.
- the UV radiators 30 radiate UV radiation which is suitable for killing microorganisms in the water. In this way, the water is disinfected.
- the surface of the cladding tubes 18 is contaminated with lime constituents and organic substances. These contaminations build up to form incrustations which absorb UV radiation and therefore reduce the efficiency of the device.
- the cleaning rings 1 are moved to and fro in the longitudinal direction of the longitudinal axis 11 over the three cladding tubes 18 by means of the holder 25.
- the electric drive electric motor 31, spindle drive 32
- a pressurised fluid for example water
- the fluid flows through the inner bore of the connection tube 26 and the channels in the holding elements 27 and enters the annular second groove 16 through the first connections 6. Subsequently, pressure is radially outwardly applied onto the scraper ring 7, so that the lips 19 are pressed against the surface of the cladding tubes 18.
- the fluid then flows from the nozzles 10 into the annular gap between the insert 17 and the cladding tube 18, where it creates turbulence that, due to the high flow velocity differences, leads to high shear forces which separate the incrustations to a substantial degree.
- the scraper ring 7 with the lips 19 then scrapes the already loosened incrustations essentially completely off from the surface of the cladding tube 18.
- the cleaning ring 1 is preferably inserted in the holder 25 and the overall assembly according to Figure 5 in such a way that in the resting position, the insert 17 faces towards the cladding tube 18 to be cleaned.
- the insert 17 then moves ahead with the nozzles 10 and effects a first treatment of the incrustation, whereas the scraper ring 7 follows behind and can scrape off the remaining incrustations. In this way, the service life of the scraper ring 7 is extended.
- the fluid exiting from the nozzles 10 flushes the incrustations out of the annular gap between the cleaning ring 1 and the cladding tube 18, which in Fig.
- Simpler embodiments of the present invention may provide that only the scraper ring 7 and the associated first groove 15 are provided in a cleaning ring 1, whilst the insert 17 and the nozzles 10 may be omitted. This configuration will then allow a functioning mode as with conventional cleaning rings, which scrape the incrustations off only mechanically. However, an improved effect is achieved, because the scraper ring 7 is pressed radially against the surface of the cladding tube 18 and the scraper ring 7 is also readjusted to compensate for any wear occurring.
- the scraper ring 7 may be made from any suitable plastic material, for example from PTFE, which is sufficiently deformable for the application described herein and which is UV resistant.
- a simplification of the described device may also consist in the fact that the electric drive (electric motor 31, spindle drive 32) may be omitted and a hydraulic drive may be provided, which is operated via the pressurised fluid used for cleaning.
- the electric drive electric motor 31, spindle drive 32
- a hydraulic drive may be provided, which is operated via the pressurised fluid used for cleaning.
- single or double acting piston/cylinder assemblies or spindle drives working in a turbine-like fashion may be contemplated.
